Subject: radv: fix stencil only clears.
If we are clearing stencil only, we still need to provide a
a valid Z output from the vertex shader, we can't rely
on the depth clear value having any meaning, as we use this
for the position output, and it could get clipped, so we
don't end up clearing anything.
Fixes:
dEQP-VK.renderpass.simple.stencil
since I added S8 support.
